CVE-2026-30893 Details
Description
Wazuh is a free and open source platform used for threat prevention, detection, and response. From version 4.4.0 to before version 4.14.4, a path traversal vulnerability in Wazuh's cluster synchronization extraction routine allows an authenticated cluster peer to write arbitrary files outside the intended extraction directory on other cluster nodes. This can be escalated to code execution in the Wazuh service context by overwriting Python modules loaded by Wazuh components (proof of concept available as separate attachment). In deployments where the cluster daemon runs with elevated privileges, system-level compromise is possible. This issue has been patched in version 4.14.4.
A path traversal vulnerability has been identified in Wazuh versions 4.4.0 prior to 4.14.4. This vulnerability exists in the cluster synchronization extraction routine, where an authenticated cluster peer can write arbitrary files outside the intended extraction directory on other cluster nodes. The issue arises because the 'decompress_files()' function in 'cluster.py' does not validate file paths, allowing for relative and absolute path traversal. Exploitation can lead to code execution in the context of the Wazuh service by overwriting Python modules used by Wazuh components. In environments where the cluster daemon has elevated privileges, this could result in a system-level compromise.
Users can upgrade to Wazuh version 4.14.4 or later, where this vulnerability has been patched.
